When measuring output ripple, it is recommended that an external ceramic capacitor (approx. 1 µF to 10 µF) be placed from the +Vout pin to the -Vout pin for single output units and from each output to common for dual output units. 2. These units should not be operated with a load under 10% of full load. Operation at no-load may cause damage to the unit. 3. Connection to the control (remote on/off) input must be made as shown in the typical Min Max connection diagram at right. This input is referenced to the -Vin pin. Input current to On <0.6 VDC to Open Circuit the pin (IC) should be between 5 - 10 mA with a maximum of 20 mA. Exceeding 20 mA 2.7 VDC 15.0 VDC could cause damage to the unit. If not used, the pin should be left open.

The value for R1 can be calculated by the formula at right. V - VD - 1 R1 = C 4. To insure proper operation over the full load range of 10% to 100% , a 100 µF capacitor IC should be connected across each output (as shown in the typical connection Input Output diagrams at right). In some applications the addition of input components Vin Vout Capacitor Capacitor may further enhance stability. Recommended capacitor values are given in the table at right. Recommended inductor values would be 4.7-120 µH 12 VDC 100 µF 5 VDC 100 µF for the input and 2.2-10 µH for the output. Output ripple on single output 24 VDC 10 - 47 µF 9 VDC 100 µF units may be further enhanced by using the CS terminal (single output 48 VDC 10 - 47 µF 12 VDC 100 µF units operated at 50% load or below should use this function). A low ESR 15 VDC 100 µF capacitor is connected between the CS pin and the -Vout pin (the anode of the capacitor is connected to the -Vout pin). Recommended capacitor values are 10 - 47 µF. If not used, the CS pin should be left open. 5. Dual output units may be connected to provide a 10V, 24V, or 30 VDC output. To do this, connect the load across the +Vout and -Vout outputs and float the output common. 6. It is recommended that a fuse be used on the input of a power supply for protection.
